Fix running of self-tests.

* debian/control (Build-Depends): Add Python dependencies to
                                  successfully run self-tests.
* debian/copyright: GPLv3 now has its own license file - use it.
* debian/watch: Set PGP signature URL.
* mandos (main): Bug fix: When running self-tests, set exit code.
* mandos-ctl (main): Cosmetic fix; use os.EX_OK instead of plain 0.
